Network Time Protocol
 (
NTP
) server to keep our clocks synchronized. We'll 
even take a look at setting up a server to act as an internet gateway for the rest of

Along the way, we'll cover the following topics:
•  Planning your IP address scheme
•  Serving IP addresses with 
isc-dhcp-server
•  Setting up DNS with 
bind
•  Setting up an internet gateway
•  Keeping your clock in sync with NTP

to manage. In the next section, we'll discuss creating such a layout, even if only to 
understand what goes into such a plan.
